## What it is
The Internet Archive BookReader is a JavaScript library for viewing scanned books online in a browser, with page-turning, zoom, search-inside, and bookmarking features. It powers the 'Read Online' experience on archive.org and Open Library and can be embedded in other sites to display digitized book images.

## Use cases
- embed an online book reader for scanned books on my website
- display digitized book pages with page-turning in the browser
- add search inside a book to a digital library viewer
- view Internet Archive books online
- build a digital library reading interface for scanned images
- add zoom and bookmarking to an online book viewer

## When to choose
- you need a battle-tested, production-proven reader for scanned page images
- you want to display Internet Archive or Open Library books
- you need an embeddable, customizable book viewer with search-inside support

## When to avoid
- you need to render EPUB or PDF reflowable ebooks rather than page images
- you need a mobile-native reading app rather than a web component
- you require a fully stable public API - v5 is in beta and may introduce breaking changes
